A further object of the invention is to 7 provide an improved screenframe construct tion embodying coacting molding members having sloping isides-fand adapted to receive 11; marginal portions of the screencovering between them whereby-the'screen covering is drawn and held tautby the interengagement 'ofsaid molding members. 7

With these and other objects in view my invention consists in theconstruction, ar-

rangement and combination of the various parts of my device, wherebytheobjects con- I templated are attained, as hereinafter more fully setforth, pointed out in my claims,

The screen includes a substantially rec- Qtangular flat'frame formed ofa pair of rails 10 and a pair of stiles 12.
